松辽盆地北部深层火山岩气藏勘探开发关键技术
Key technologies for exploration and development of deep volcanic gas reservoirs in northern Songliao Basin
摘要
Abstract
Volcanic gas reservoirs in Xujiaweizi Rift of northern Songliao Basin are the main reservoirs of Xushen Gas Field,characterized by diverse lithology and high heterogeneity of reservoirs,and facing a series of technical difficulties and challenges such as unclear understanding of gas enrichment laws,difficult prediction of high-quali-ty reservoirs,complex variation laws of gas well productivity and well-controlled reserves,and difficulty in tapping remaining gas potential.Analysis of evolution process of volcanic gas accumulation,description of volcanic eruption stages,prediction of effective reservoirs,evaluation of well-controlled reserves and description of remaining poten-tial are performed to develop techniques including accumulation evaluation of volcanic gas reservoirs,fine charac-terization of three-orders volcanic bodies,dynamic reserves evaluation and remaining potential evaluation and tap-ping.2 types of dynamic reserves models of"low permeability growth type+high-permeability stable type"are clari-fied,as well as policy limits for potential tapping technology of combining dynamic and static"6 parameters".Gas generation period of source rock and gas accumulation period are determined,gas enrichment is clarified to be con-trolled by 4 factors of source rock,fracture,reservoir and cap rock,fine characterization of internal structure of vol-canic rocks is realized,2 types of dynamic reserves growth laws of gas wells are clarified,and potential tapping technical solutions for different types of remaining gas are formed.Based on a series of key technical innovation for exploration and development of volcanic gas reservoirs,natural gas production of Xushen Gas Field increases year by year.The series of technology is popularizing applied in Daqing Oilfield with significant results,effectively sup-porting continuous and stable growth of natural gas production in Daqing Oilfield.The research provides effective technical guidance for exploration and development of similar type of gas reservoirs.关键词
